This is the Steps for all of these problems shown below these are Limiting Reagent Rxn Problems- Go through all of them and tell me the correct answers and follow these steps below. In order please.Check if provided equation is balanced, or write the chemical equation and balance it showing all work or explaining each step taken and why. Also Find the molar mass of needed reactants and products (Don’t round or use google values or you may have errors in your final answer) Also Find theoretical yield in grams for each product using each provided amount of reactant. And also Determine what question is asking you to find and provide answer in correct format. This is an example of how each problem should be answered: X=correct answer with sig figs unit = mols, grams, molecules, etc compound name solved for 58.5g of H2O. Also look for : limiting and excess reactant (by name or mass amount left over) theoretical yield and percent yield.

1.

a. The balanced chemical equation is: Cl2 + 2NaOH → NaCl + NaClO2 + H2O
b. The molar to molar ratio of sodium hydroxide to sodium chloride is 2:1.
c. The name of NaClO2 is sodium chlorite. The two ions it forms are Na+ and ClO2-.

2.
a. The balanced chemical equation is: 2H2 + O2 → 2H2O
b. This is a synthesis reaction.
c. If you started with 250.0 grams of hydrogen, you would create 250.0 grams of water.
d. If you started with 250.0 grams of oxygen, you would create 125.0 grams of water.
e. Hydrogen is the limiting reactant.

3.
a. The limiting reagent is ammonia and the theoretical yield of nitric oxide is 5.70g.
b. 2.65g of excess reagent remains (ammonia).
4.
a. The balanced equation is: 3Si + 4N2 → 2Si3N4
b. 117.5 grams of silicon are needed to form 98.5 grams of silicon nitride.
c. Silicon is the limiting reagent and nitrogen is the excess reagent.
d. 25.5 grams of additional nitrogen are needed to produce 98.5 grams of product.

5.
a. The balanced chemical equation is: 2S + 3O2 → 2SO3
b. The theoretical yield of sulfur trioxide is 229.5 grams.
c. The percent yield of sulfur trioxide is calculated by (actual yield/theoretical yield) x 100%. In this case, it is (246.6/229.5) x 100% = 107.5%.

Can you put the answers you got above with sig figs please? That would really help me.
